Special Purpose Heat Shrink Tubing, WRSJD

Model: WRSJD

Adhesive lined cross-linked polyolefin heat shrink tape

WRSJD is adhesive lined cross-linked polyolefin heat shrink tape specifically designed for sealing joints on spiral, flexible or flat oval ducts used in heating, ventilating, air conditioning and exhaust recovery systems.


Features
  • Shrink ratio: 1.4:1
  • Eliminating air leakage in vacuum and ventilation systems
  • Sealing against moisture ingress and other contaminants
  • Strong adhesive bonding to galvanized steel, aluminum and stainless steel
  • Effective and reproducible sealing ensures resistance to bending, vibrations and other mechanical stresses over a wide range of temperatures
  • Application process is quick, simple and clean
  • Continuous operating temperature: -45℃~125℃
  • Fully shrink temperature: 120℃
  • Color: black, red, green, yellow
